On the sheet place peppers lightly coated in oil and lightly salted, and roast for 10 minutes. Remove and set aside to cool. Leave oven on.In medium skillet, fry garlic and chorizo until cooked. Drain, and return to skillet. Add red onion, corn, allspice, and cumin, blend, and cook until onions almost translucent. To this, add the pimento peppers, scallions, and cilantro and blend well. To this add the rice and lime juice and blend well. To this add the queso fresco and 3 ounces of the shredded Manchego and blend quickly.Stuff roasted Poblanos with rice chorizo blend to sufficiently stuff each. This will use most or all of the stuffing. Place stuffed peppers on baking sheet.Place baking sheet with peppers in oven for 15 minutes.
